Hi Guys,
For several months I was finding my HTC Desire wanting in terms of playing my media files on my TV. After some research I stumbled upon an app in the Marketplace called Twonky that transforms the Desire into a media server that my DLNA capable TV can connect to TV over my home wireless network. So I can now watch all my videos, photos and also play music files from the Desire on my TV.
Cheers.
